Credential Communication System Privacy Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for exchanging and verifying credential sets, such as those on passports, driving licenses, and payment cards, often compromise the privacy and authenticity of the information, as the data is vulnerable to unauthorized access and copying during automated systems interactions.
Innovation Solution
A system and method that allows controlled credentials to be communicated to a network endpoint while maintaining their privacy, using a server with presenter records containing unique identifiers and secret keycodes, and a shared keycode mechanism to authenticate and authorize the release of credential sets to designated recipients, ensuring the authenticity of both the presenter and the credential set.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If credential sets are released during automated system interactions, then data exchange efficiency is improved, but privacy and authenticity are compromised due to vulnerability to unauthorized access and copying
Solution Approach 1:
The patent introduces a credential management system with issuing authorities, registrars, and verifying systems that act as intermediaries between credential holders and automated systems. These intermediaries manage credential lifecycles securely, allowing automated data exchange while maintaining privacy through selective disclosure and authenticity through cryptographic verification mechanisms.
Solution Approach 2:
The patent employs cryptographic copying mechanisms where credential data can be securely replicated and verified without compromising the original. Digital signatures and hash functions enable verification systems to create and validate copies of credential information, ensuring authenticity while allowing efficient automated verification without exposing sensitive original data.
2Speed
If credential sets are stored in automated systems, then verification speed is improved, but security is worsened due to increased attack surfaces and unauthorized access risks
Solution Approach 1:
The patent segments credential data into multiple components: credential holder information, verifying system data, and issuing authority records distributed across different systems. This segmentation prevents any single system from containing all sensitive data, reducing the impact of potential breaches while enabling fast verification through distributed cryptographic validation.
Solution Approach 2:
The patent implements preliminary credential verification and validation by issuing authorities before credentials are deployed to automated systems. Registrars pre-verify credential authenticity and register them in secure databases, so that during automated interactions, only pre-validated credentials need verification, significantly reducing verification time while maintaining security through prior authentication.
3Adaptability or versatility
If traditional credential exchange methods are used, then system compatibility is improved, but fraud vulnerability increases due to lack of authentication mechanisms
Solution Approach 1:
The patent transforms traditional credential parameters by adding cryptographic elements: digital signatures, unique identifier structures, and verification codes. These parameter changes maintain compatibility with existing credential formats and systems while introducing authentication mechanisms that prevent fraud and cloning through cryptographic verification rather than relying solely on traditional format compatibility.
Data Source
AI summary
A system and method for conducting transactions involving the communication of credentials connected to an entity or an individual, known as the presenter to a permitted destination, known as the network endpoint (110) following a request from an accepter while maintaining the privity in said credentials. The system includes presenting appliances (108) and accepting appliances (109) that communicate with a controlling server (101). The controlling server receives communication from the accepting and presenting appliances that contains a secret keycode exclusive to the individual or presenter, presenter identifiers and a shared keycode and if the communications are matched, credentials specific to presenter identifier is permitted to be released to a known network endpoint.
